AXE is designed for fast simulation of XCore programs. AXE doesn't attempt to be cycle accurate. Instruction execution timing is approximate. AXE is experimental and likely to contain bugs.
A single thread doing mainly arithmetic operations executes at the equivalent of over 100MIPs on my 2.3 GHz Core 2 Duo machine. Programs utilizing ports, chanends and threads will run, although this isn't particularly well tested.
